Acerca de Tania Australis

Descripción

Tania Australis (Mu Ursae Majoris) is a gigante roja of tipo espectral M0III at magnitude 3.05 en la Osa Mayor. Located a unos 230 años luz de la Tierra, it has a cool temperatura superficial of roughly 3,900 K and a distinctly orange-red color. It forms the southern member of the 'Tania' pair with Lambda UMa (Tania Borealis), representing one of the Bear's hind paws.

Consejos de Observación

Mu UMa lies below the Carro Mayor's bowl, forming a close pair with Lambda UMa (Tania Borealis) about 2 degrees to its north. The two Tania stars make an attractive binocular pair with contrasting colors — Mu is orange-red while Lambda is white. They represent the Bear's southern hind foot. Mejor observación from February through July when Ursa Major is high overhead.

Historia

The name Tania Australis means 'the southern Tania' in Latin/Arabic hybrid form. 'Tania' derives from the Arabic 'al-thaniya,' meaning 'the second' (leap of the gazelle). The three pairs of stars in the Bear's feet (Talitha, Tania, and Alula) were seen en el Altarb astronomy as three successive leaps of a gazelle.

Datos Curiosos

The three pairs of stars forming the Great Bear's hind legs — Talitha (Iota/Kappa UMa), Tania (Lambda/Mu UMa), and Alula (Nu/Xi UMa) — were imagined en el Altarbic astronomy as the tracks of a bounding gazelle. Each pair represents one leap, creating a charming alternative interpretation of these stars.
